Ectatomminae Emery

= Heteroponerinae Bolton new synonym

Diagnosis: Presenting the characters of ‘poneromorph’ subfamilies described by Bolton (2003: p.40). Clypeus broadly inserted between frontal lobes ( Bolton 2003); anterior clypeal margin with a narrow lamellar apron ( Bolton 2003). Torulus not completely fused to frontal lobe ( Bolton 2003). Antenna with 12 segments ( Bolton 2003). Pronotum with the humeral corners angled, forming a distinct delimitation between the anterior and lateral margins ( Lattke 2004). Antero-ventral angle of pronotum triangular ( Feitosa 2015). Pretarsus without arolium ( Lattke 2004). Petiole pedunculate ( Keller 2011). Petiolar node as wide or wider than long ( Feitosa 2015). Subpetiolar process very well developed, occupying more than onethird of the ventral portion of the petiolar sternite ( Feitosa 2015). Helcium projecting from about midheight of the anterior face of abdominal segment III. Abdominal segment IV presclerites separated from the rest of segment by a constriction or slight thickening ( Lattke 1994). Fourth abdominal tergite arched and larger than the sternite, giving the segment a curved appearance ( Keller 2011).
